How to use SYsLinux to make USB boot

I have an Intel N4200 evaluation board that only supports UEFI startup.I built my own file system and wanted to boot with SysLinux, but I didn’t know how to do it. I know that the main configuration is written in syslinux.cfg, but I don’t know what other file configurations are needed.
Please help me, thank you!

Hi Zhyg,

Welcome to our forums.

Did you try booting up with the syslinux.cfg you created? Did you got any error messages that point to missing configuration? If so, please provide us these outputs, so we can understand your situation better. The contents of the cfg file may also be useful.

Thank you for your reply.
By learning the SysLinux wiki and experiment, I finally boot up with SysLinux.But I ran into a new problem.
Each time the kernel and Initrd are loaded using SysLinux, the following is printed on the screen:
loading vmlinuz-4.15.0-107-generic…OK
loading initrd.img-4.15.0-107-generic…OK

I want to hide these two sentences to load the print information.
